TotalStorage DS8000™
The IBM TotalStorage DS8000 series incorporates IBM POWER5™ processor technology in a dual 2-way
processor-complex offering the DS8100 (2107-921), or a dual four-way processor-complex offering, the
DS8300 (2107-922 and 2107-9A2). The Model 9A2 enables the creation of multiple storage system LPARs
(logical partitions). The DS8000 offers up to 32 host adapters. This can be an intermix of ESCON® and
Fibre Channel/FICON adapters, further increasing your ability to share your disk storage. The DS8000 is
designed and implemented with component redundancy to help eliminate single points of failure. For data
protection the DS8000 supports RAID 5, RAID 10 and optional Advanced Software features, IBM
TotalStorage FlashCopy, Metro Mirror, Global Mirror, Metro/Global Copy.
The DS8100 (2107-921)offers a dual 2-way processor complex and holds up to128 disk drives for a
maximum capacity up to 38.4 TB. Fibre Channel disk drives are available in 73 GB (15,000 rpm), 146 GB
(10,000 rpm), and 300 GB (10,000 rpm) capacities. The DS8100 also supports up to 128 GB of processor
memory and up to 16 Fibre Channel (or ESCON/FICON for zSeries Servers) adapters for host or SAN
attachment. With an optional expansion unit (2107-92E), a single Model 921 solution supports up to 384
disk drives, for a total capacity of up to 115.2 TB.
The DS8300 (2107-922) offers a dual four-way processor complex and holds up to128 disk drives for a
maximum capacity of up to 38.4 TB. Fibre Channel disk drives are available in 73 GB (15,000 rpm), 146 GB
(10,000 rpm), and 300 GB (10,000 rpm) capacities. The DS8300 (2107-922) also supports up to 256 GB of
processor memory and up to 16 Fibre Channel (or ESCON/FICON for zSeries Servers) adapters for host
or SAN attachment. With one or two optional expansion units, the 8300 supports these configurations:
With one Model 2107-92E expansion unit, the Model 922 supports up to 384 disk drives, for a
maximum capacity of up to 115.2 TB, and up to 32 Fibre Channel (or ESCON/FICON for zSeries
Servers) adapters for host or SAN attachment.
With two Model 2107-92E expansion units, the Model 922 supports up to 640 disk drives, for a
maximum capacity of up to 192 TB, and up to 32 Fibre Channel (or ESCON/FICON for zSeries
Servers) adapters for host or SAN attachment.
The DS8300 (2107-9A2) offers a dual four-way processor complex and holds up to128 disk drives for a
maximum capacity of up to 38.4 TB. Fibre Channel disk drives are available in 73 GB (15,000 rpm), 146 GB
(10,000 rpm), and 300 GB (10,000 rpm) capacities. The DS8300 (2107-9A2) also supports up to 256 GB
of processor memory and up to 16 Fibre Channel (or ESCON/FICON for zSeries Servers) adapters for host
or SAN attachment. With one or two optional expansion units, it scales as explained here:
With one Model 2107-9AE expansion unit, the Model 9A2 supports up to 384 disk drives, for a
maximum capacity of up to 115.2 TB, and up to 32 Fibre Channel (or ESCON/FICON for zSeries
Servers) adapters for host or SAN attachment.
With two Model 2107-9AE expansion units, the Model 9A2 supports up to 640 disk drives, for a
maximum capacity of up to 192 TB, and up to 32 Fibre Channel (or ESCON/FICON for zSeries
Servers) adapters for host or SAN attachment.
The DS8000 models are populated with Disk Drive Sets (#2xx6 features) with16 disk drives per set.
Different Disk Drive Sets can be intermixed within the same model.
The DS8000 offers extensive connectivity support, including Fibre Channel, FICON, or ESCON across a
broad range of server environments including zSeries, pSeries, IBM eServer p5, iSeries, and xSeries
servers, servers from Sun and HP, and non-IBM Intel-based servers.
